摘　　要：以试验方法改变日常水汞观测中涉及的化学试剂用量,来分析水汞观测的干扰因素,实验数据表明:硫酸试剂是影响水汞观测结果稳定性的主要因素之一,试剂量与观测结果(汞含量)成正相关关系;而高锰酸钾、氯化亚锡试剂对观测结果几乎没有影响。The interference factors of water mercury observed are analyzed by changing the amount of the chemical reagents involved in the daily water mercury observations. The experimental data show that the sulfuric acid reagent is one of the main factors affecting the observations. There are positive correlation between the observations and sulfuric acid reagent we added, and mercury content increases with increasing amount of sulfuric acid reagent and decreased with the reduction in the amount of sulfuric acid reagent added. In addition, potassium permanganate and stannous chloride almost has no effect on the experimental results.
